Betaine supplementation, performance and HCTL
I presented to the Exercise Science Department last week. Next week I'm presenting at the med center to the muscle physiology department. The ex sci presentation was recorded...I had to dumb it down a bit for the majority of undergrads in attendance. Aside from running low on time, enjoy.

Subbed to remind myself at a later time to watch the video.

I've decided to invest in making betaine TMG, beta alanine, and l citrulline staples in my regimen. I'm currently getting my TMG from test powder or condense. I'm waiting for SNS to release their bulk powder!
I know the dose is 2.5g daily, should I decide to combine test powder and condense at some point, what is the maximum dose, 5g? (Assuming test powder has 2.5g or less)

All the research showing benefit has been done with 2.5g. I don't see a reason to go over 2.5-3g. The side effects at those dosages seem to be minimal, mostly GI distress...but we saw improvements in large men (>210 lbs) with 2.5 grams... So i don't think dose-mass ratio is a huge deal.

I watched about half of the video, didn't have time for the whole thing. I've been reading a lot about betaine increasing igf-1 decently while slightly increasing gh and lowering cortisol. Do you have any info on this? Here's one of the charts I found from a two week study

The review was accepted and will be published in the journal Amino Acids. Keep a look out.

How is it best dosed?
Best to split dosing or take all at once pre-workout?

Effects of betaine on performance and body composition: a review of recent findings and potential mechanisms.

Betaine is a methyl derivative of glycine first isolated from sugar beets. Betaine consumed from food sources and through dietary supplements presents similar bioavailability and is metabolized to di-methylglycine and sarcosine in the liver. The ergogenic and clinical effects of betaine have been investigated with doses ranging from 500 to 9,000 mg/day. Some studies using animal models and human subjects suggest that betaine supplementation could promote adiposity reductions and/or lean mass gains. Moreover, previous investigations report positive effects of betaine on sports performance in both endurance- and resistance-type exercise, despite some conflicting results. The mechanisms underlying these effects are poorly understood, but could involve the stimulation of lipolysis and inhibition of lipogenesis via gene expression and subsequent activity of lipolytic-/lipogenic-related proteins, stimulation of autocrine/endocrine IGF-1 release and insulin receptor signaling pathways, stimulation of growth hormone secretion, increased creatine synthesis, increases in protein synthesis via intracellular hyper-hydration, as well as exerting psychological effects such as attenuating sensations of fatigue. However, the exact mechanisms behind betaine action and the long-term effects of supplementation on humans remain to be elucidated. This review aims to describe evidence for the use of betaine as an ergogenic and esthetic aid, and discuss the potential mechanisms underlying these effects.
